The Playmakers

DE Derrick Morgan

On Philip Rivers’ first dropback against Tennessee last year, Morgan steamrolled right tackle Jeromey Clary and slammed into Rivers. Also against Clary, he later used a spin move to record a 2.9-second sack of Rivers. Will likely line up against the right tackle, either Michael Harris or D.J. Fluker (concussion) .

CB Alterraun Verner

He has two interceptions this year, returning one for a touchdown. Against the Chargers last September, the 5-foot-10 Verner picked off Rivers' under-pressure lob to 6-5 Malcom Floyd. Joining him on the starting defense is fellow UCLA alum Akeem Ayers, an outside linebacker.

WR Nate Washington

Jake Locker’s favorite target, Washington (6-1, 187) runs precise routes. He led the Titans in receiving yards the last two years; now 30, he is again first in the same category. Chargers cornerback Shareece Wright, questionable with a hamstring injury, is drawing lead receivers.
